I had probably 100 or so custom brushes that's I've worked on over the past 2 years. I opened up Photoshop today and they are all gone, replaced by the default photoshop brush packs.
I don't know if I made any of them presets, I tried looking for brushes in the presets folder but I didn't find anything. I'm not sure if there is any way to get them back but I also don't know that much about photoshop so please help.
